CPS clearly is not your best resource and certainly is not your only resource. It is essential to have the injuries (bruises, etc.) documented by a neutral party, best party is the child's physician/nurse practitioner. However, based on the child's words describing how he received the injuries and your own observations of the injuries, you should be able to get an emergency temporary order of protection (or some similarly named document in your jurisdiction). In addition, you must contact immediately your family law attorney --- the court will always entertain motions to modify custody especially when the safety of a minor is at issue. Surely your attorney will be able to set emergency motions/get temporary orders/take immediate action to protect your son -- both now and in the future.
As you know, this matter is too important not to act right now!
